PART VI - FLIGHT PLANNING CHARTS

	    The climb data is shown on the left of each chart at the
	    beginning of a flight and the optimum range speeds and
	    the approximate speeds at 93 per cent. at different
	    altitudes are shown graphically on the right of each chart.
	    Several scales for "lb. fuel remaining" are given at the
	    bottom of each chart to take account of the different
	    weight of fuel in the tanks according to the sp. gr. of
	    the fuel used.
                 Use of the charts
           (v)  To obtain the minimum amount of fuel required to fly
	    a given distance, select the point farthest to the left of
	    the chart on the appropriate distance line (by inter-
	    polation if necessary) and read off the "lb. fuel remain-
	    ing" on the appropriate line vertically below.  From the
	    figure obtained deduct the fuel required for descent and
	    landing and subtract the total from the fuel weight at
	    take-off.
          (vi)  To obtain the maximum distance it is possible to fly for
	    a given fuel load, inspect the appropriate chart to find
	    the height at which the maximum distance for that
	    amount of fuel is obtainable, then subtract the descent
	    and landing allowances for that height.  The resulting
	    reading when applied to the "fuel remaining scale" gives
	    the equivalent distance on the distance/altitude scale.
